iperf, Iperf, or iPerf, is a tool for network performance measurement and tuning. It is a cross-platform tool that can produce standardized performance measurements for any network. iperf has client and server functionality, and can create data streams to measure the throughput between the two ends in one or both directions. [2]
A feature of iftop is that it can suppress display of DNS traffic by using a filter code such as "not port domain", or switch it off entirely, by using the -n option or by pressing "n" when the program is running. Using the -F option makes it possible to show packets entering and leaving a given network.
Netperf is a software application that provides network bandwidth testing between two hosts on a network. It supports Unix domain sockets , TCP , SCTP , DLPI and UDP via BSD Sockets. [ 1 ] Netperf provides a number of predefined tests e.g. to measure bulk (unidirectional) data transfer or request response performance.
It measures the network throughput between two systems using the TCP or optionally UDP protocols. [1] It was written by Mike Muuss and Terry Slattery at BRL sometime before December 1984, [ 2 ] to compare the performance of TCP stacks by the Computer Systems Research Group (CSRG) of the University of California, Berkeley and Bolt, Beranek and ...
In computing, netstat is a command-line network utility that displays open network sockets, routing tables, and a number of network interface (network interface controller or software-defined network interface) and network protocol statistics. It is available on Unix, Plan 9, Inferno, and Unix-like operating systems including macOS, Linux ...
In interactive mode, it displays the network status on the user's terminal. In Web mode, it acts as a web server, creating a HTML dump of the network status. It supports a NetFlow-sFlow emitter-collector, a Hypertext Transfer Protocol (HTTP) based client interface for creating ntop-centric monitoring applications, and RRDtool (RRD) for persistently storing traffic statistics.

IPVS is incorporated into the Linux Virtual Server (LVS), where it runs on a host and acts as a load balancer in front of a cluster of real servers. IPVS can direct requests for TCP- and UDP-based services to the real servers, and make services of the real servers appear as virtual services on a single IP address .
